Product scienceHow Glyphosate 41% SL Works: Mode of Action
Bayer Roundup is a non-selective, systemic herbicide. This means it travels through the entire plant's system to deliver a complete, permanent kill. Here is the step-by-step process:
- Rapid Absorption: The specialized liquid spray cuts through the waxy outer layer of the weed's leaves and stems, absorbing quickly into the plant.
- Deep Translocation: Once inside, the chemical travels downward through the plant's vascular tissue, reaching all the way to the deepest root networks.
- Metabolic Shutdown: Glyphosate blocks a vital enzyme (EPSP synthase) that the weed needs to create proteins. Without these proteins, the weed starves, turns yellow, and completely dies.
Because it targets an enzyme found only in plants, it effectively clears the land while binding tightly to the soil afterward, preventing it from leaching away easily.
Useful detailsTarget Crops & Problem Weeds

How to applyBayer Roundup Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop / Area | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea Plantations | 1000 - 1200 ml | 200 L | 5 - 6 ml | 21 Days |
| Non-Cropped Areas | 1000 - 1200 ml | 200 L | 5 - 6 ml | N/A |
| Paddy (Pre-Planting) | 1000 ml | 200 L | 5 ml | N/A (Apply 3 Days Prior) |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
Useful detailsHow to Apply Glyphosate: Spraying Best Practices
- Timing: Spray on a clear, rain-free day. Aim for the cooler hours of the early morning or late afternoon to prevent the chemical from evaporating too quickly.
- Mixing: Bayer Roundup already includes a premium surfactant package. Do not mix with hard water, extra surfactants, or muddy water, as this can reduce its weed-killing power.
- Coverage: Use a high-volume knapsack sprayer equipped with a flat fan nozzle. Ensure you are spraying young, actively growing weeds with an even, overlapping pattern.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Keep away from water bodies and neighboring healthy crops.
Use with careSafety Warnings & Disclaimer

Frequently Asked Questions About Bayer Roundup
1. What makes Bayer Roundup better than cheap generic glyphosate?
Bayer Roundup contains highly advanced, built-in surfactants. This means it sticks to leaves better, penetrates deeper, and won't wash away in the rain as easily as cheaper brands that require you to buy and mix your own additives.
2. Will this herbicide kill my crops too?
Yes. It is a non-selective herbicide, meaning it will kill almost any green plant it touches. It should only be used in non-cropped areas, tea plantations, or carefully applied before you plant your actual crops.
3. What happens if it rains right after I spray?
Thanks to its premium formulation, Bayer Roundup is "rainfast" in just two hours. As long as it has been two hours since you sprayed, rain will not wash away the chemical or reduce its effectiveness.
4. How long does it take for the weeds to completely die?
You will typically see the weeds turn yellow and wilt within a few days. Complete root death takes anywhere from a week to a few weeks, depending on the weather and how tough the weed is.
5. Can I spray this over a standing paddy field to clear weeds?
Absolutely not. Spraying this on a standing crop will result in total crop failure. For paddy fields, it must be used strictly as a pre-plant application at least three days before you plant your seeds.
